The upcoming MacBook Pro 2016 is now believed to come with the super-fast second-generation USB 3.1 after it was found out that the macOS Sierra beta contains a code  that supports for this type of USB port. And it is very possible that future Mac devices will sport the same type of port as well. 

According to 9To5Mac, it found the code for the super-fast USB 3.1 in a localizable text string in the beta version of macOS Sierra. The Apple-centric tech site pointed at entries for “Super Speed Plus” and “Up to 10 Gb/sec” to support its claim that the Cupertino tech giant is looking to build Mac hardware with the second-generation USB 3.1 with transfer speeds of up to 10Gb/s. 

Current Mac devices only support second-generation USB 3.1 with transfer speeds of up to 5Gb/s, as per MacRumors. OS X El Capitan is also void of support for this 10Gb/s type of port. Hence, it is safe to assume that the new Mac devices, including the MacBook Pro 2016, will have USB 3.1 ports that have super-fast transfer speeds. 

Based on history, Apple has always been swift in bringing the latest USB and Thunderbolt ports to its Mac devices for maximum performance. Thus, the addition of the 10Gb/s variant of USB 3.1 does not come as a surprise. The same thing can be said of Thunderbolt 3, which is also rumored to be part of the MacBook Pro refresh this year. Thunderbolt 3 would be a great addition to the Mac device’s hardware, since it supports both the 10Gb/s USB 3.1 and the DisplayPort 1.2.

Almost two weeks ago, it was revealed that the MacBook Pro 2016 will likely come with a small touchscreen OLED display that would replace the top functions keys on the keyboard of the laptop. This claim is already backed by codes found in the macOS Sierra, as noted by 9To5Mac in a separate report. 

There is still no word on the possible release date of the MacBook Pro 2016, but some sources are claiming that Apple will mostly launch the new laptop this October or November — possibly the same time as the official release of the macOS Sierra update.
